Application filed April 5, 1912. `Serial No. 688,598.

T0 all ,whom 'it may concern.'

Be it known that I, Encino I. LA CHA-A reLLn, a citizen ot' the United States, residing in Beverly, county of Essex, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Machines for Turning and Belasting Shoes, ot which the following is a specification, reference being had to the drawings accompanying the same and forming apart thereof.

My invention relates to improvements in machines -tor turning-the uppers upon the -sole of what are termed turn shoes, and for relasting the shoe.

The objects oi' my invention are as iollows :--To so arrange a turning and relastingmechanism that the more laborious portions of the work maybe accomplished by the foot of the operator; to so arrange the mechanism that the same operating parts of the device may be used for both operations; and further to provide means to assist the operator in drawing the -ore part ol' the shoe upon the forepart of the last 1n v the operation of relasting, and to provide a vent to the toe of the shoe so that the air confined therein may easily esca-pe.

In the drawings which accompany this i speciiicationFigure 1 shows a trent elevation of the machine with the clamping de- .ice closed, 'and a last in the relasting portion of the machine, and a shoe partially relasted; F ig. 2 is a side sectional elevation of the machine showing the parts in the same position as they arein Fig. 1; Fig. 3 shows a portion of the upper part of the machine comprising the clamping portions with the cooperating clamping portion open; Fig. 4 is a sectional view looking downward upon the machine taken at line 1fi, Fig. 2, but with the last and shoe' removed.

In the drawings illustrating my device, 1 represents the bearing portion designed to support the machine by being fastened to a bench or other supporting means. 1A tube 2 is secured in the bea-ring portion and eX- tends downwardly to the iioor and has secured upon its lower end the base-plate There is secured in the upper portion ot the tube 2 a rod 4L which extends upwardly and has pivoted in its upper end a roller 5. A sleeve 6 is slidably mounted upon the rod 4 near its upper end and has formed upon it the clamping-member 7. There is secured to the sleevev 6 the lcooperating clamping member 8 having the clamping surface 9 formed upon its free end. At the inner ends' of the clamping-member 8 there are formed circular slots 10 designed to be mounted upon the bearing screws 11, 1`1, in such way that the cooperating clamp S will move the length of the slot upon the bearing-screws 11, 11, when the clamping surface 9 is moved to clamp the sole of a shoe between it and the clamping surface 7. The sleeve 6 is held in its uppermost position by means of a compressible spring 12 which is mounted upon the rod 4, and bears at its lower end upon the adjustable collar 13, the collar being adjustably secured by means of a set screw 14. The spiral spring 12 is of sutiicient tension to hold the sleeve 6 in its uppermost position. There is extending downwardly from the inner end of the cooperating clamp 8 a bracket 15 to which there is secured two adjustable rods 1G, 16,- by means of the screws 15a, 15a, which rods extend downwardly and are fastened by suitable means to the treadle portion 17. Thetreadle portion 17 is moved downwardly by means of the outwardly extending portion 18 arranged to be operated by the foot of the operator.

The sleeve G is provided with a locking device to prevent its movement during the ating clamp 8. This locking device consists of the pivoted bell-crank-lever 19 which is pivoted to the sleeve 6 by means of the pivot 20 and has a locking-bolt 21 pivoted-to it, which locking-bolt is of sutlicient length to extend through the wall of the sleeve 6 and into the recess 22 formed in the upper end of the rod 1. The bellfcrank-lever 19 is provided with a recess 23 to receive the lever 21ml.. The lever 2st is pivoted at the point 25 upon the sleeve 6.

Extending crosswise from the lever 24: is

a rod 26, shown in Fig. 1, having its ends projecting outwardly so that the ends of the projecting parts 27, 27, will contact with them when the clamping member 8 has been moved to the position shown in Fig. 2, and thereby cause the upper end or the lever 24 to contact with the lever 19 and withdraw the locking-bolt 21.

The two adjustable rods 16, 1.6,' are provided with adjustable sleeves 28 and adjusting screws 29, 29, for the purpose of adjust ing the amount of throw ofthe clampingmembers 6 and 8. The weight of the clamping members 6 and 8, and of the other slidable portions of the mechanism lare counterioo V upper end of the tube.

ina-aragosta balanced by ineens of the weight which is arranged toreely slide up and down inside of the tube 2. The Weight 30 is attached to thet eadle 17 by means of the asteniirig4 consists oi' a tube mounted in the braeh'et of thebeering portion i. The tube is open at its Upper enti and is adopted to receive the socket which is adapted to receive the heel oi the lest While the Shoe is being relasted. The socket 36 is provided with two adjusting 3?', 3?, which may be adjusted in and out in the slots 38, 38, to enable the setting of the inst toward or away from the machine. The socket 3G is inounted upon the upper end of the tube 3e. This socket 36 is made of .ieizibie steei so that its upper ends Will enter the notches 39 Yformed in the 'saddle portion 0. By this method of fastening, the socket 36 may be sprung in or out to dierent Widths between the upright portions to aeeoimnodete lasts having dit ferent Widths of heel portions. tlhere is mounted upon the-upper end of the tube 3e a sliding-bloei; 41 which is fitted, to slide n and down freely on said rod 34.' The sli ing-block 41 is counterbalaneed by means of the weight 42 secured to it by the oord 43 v which runs over a suitable uiley in the T e block 41 is provided with five let flexible springs lili, 1li, ete. rThesey springs are tiet quite thin and flexible so that they may be bent in to substantially conform to the shape of the fore part of o last, as shown in Fig. l. The purpose of these springs -Wili be more fuliy described hereafter.

The bolt 5 is adefpkied to enter e hole 48 formed in the front oit the tube 34 so as to lock the block il at ithe position it assumes when' the end ot' the pin arrives et a point Where it will enter the hole 48. The block 41 is moved downi'vard by means of the rod i9 which is attached to theilug extending 'backward neer its bottom portie-n. The

lower end of the rod 49 is secured in the.

lug 5l formed upon the treadle 17. As the treadle 1.7 is moved downward it will puii the block 411 'down until the pin 45 enters the hole 4S. The bloc il may be moved downward still farthef by ineens of the treadle 52 which is fastened to bioelf e?. by ineens of the rod Trie v i further movement oi the bloeit sii Wifil b`j more fully explsined hereafter.

To assist the operator in puliing doe'nwardiy upon the lost in the ol of relzisting.. l provide the two friction elio-- ing; members (32 and These 'n'ieinbers mede out of pieees ol spring steel. se they will have more or less elasticity, one, their inner faces have secured to them pieces of rubber so that they will oline' with. more or less friction to the sides of the fore port of e shoe and the edges of the sole, and es before stated, assist in drawing the fore part or". the shoe downwardly upon the last in the operation of relssting.

The operation of turning and rei ting s.

The pin. 2i prevents the clamping member 6 from moving down wardiy upon the :rod e until the sole has been partially bent end the heei portion bent or broken over the soie by means of the hand and the levers 54, 56 and 5'5". After the heei portion is turned the iooiringpin with1 drawn from. the hole the rod fi means of the levers 19, 2131. and projeetions 2'?, iii" and the clempingmiembers 6 end moved down to bend the sole end. complete turning of the tore part of the shoe., stop is pivoted to the `portion 18 pi vent the foil movement of the treedlp at t first operation and so that the roile not be pushed. vioientiy shoe. ,'When the te S,the operator moi/es n u to swing; the

a set screw, so that the collar may set at any position on the rod 67 and contact with the vtop of the tube 2 so as to limit the downward movement, as before stated, of the portion 6. When the fore part of a shoe upper is turned to complete the turning of the upper of the shoe upon the sole, the treadle is released and immediately moves upwardly until the clamping members assume the position shown in Fig. 3, their upward movel ment being accomplished by means of the spring 12 and the counterweight 30.

In the operation of r'elasting a shoe, the movement of the clamping members 6 and 8 by meanslof the treadle 1.7 is used to relast ya shoe in the following manner :-When the relasting and clamping members are in the position shown in Fig. 3, the frictionsprings 62 and 63 are swung backwardly to the position shown. When in this position the toe of the last is inserted between the springs 44 and moved into'the position that the last is shown inin Fig.' 2, although in Fig. 2 the clampingemember Shes been moved to apoint where the friction-'surfaces 62 and 63 are brought in contact with the shoe upper and sole edges; but before-this vmoven'ient of the clamping-member 8, the op era'torpla'ces the last inp'osition, as before described, and with his hands bends the f springs' 44, etc., inwardlyuntil they assume the position shown in'Fig. 1.' IWhen in this position the upper of a shoe may be drawn down over-the ends or" the springs and the fore'part of the' last until it'assumes the position shown in Fig. 2, when the operator placesv his foot on the portion 18 of the treadle 17 and pushes the treadle downwardly. The first movement of. the treadle causes the clamping member 8 to move on the studs 11, 11, andcauses the friction springs'62 and 63'to move in the arc of'a circle downwardly and'toward the top ofthe last and into'the position vshown'in Fig. 2. Further movement of the treadle draws the springblock 41 downwardly and moves the frictionsprings" 62 and 63 downwardly, and by the friction' of said springs 62' and 63 and ,the flat -llexible springs 44f'i'nside theshoe, 55l

the upper is drawn downwardly upon the last until'the toe of thel last projects fully into the toe of the upper". When this is accomplished, thel block 41 has' been moveddown to a point where the spring-bolt 45 will enter the hole 48 in the tube 34. Thereupon, the operator :removes his .foot from the treadle 17 land allows ity t0 move upwardly until the clamping-member V8 and the friction spring members 62 and 63 assume the position shown in Fig. 3. There inside of the upper of the shoe away from the last sufficiently to prevent air being retained inthe point of the shoe, or in other words they serve as a vent in the toe of the shoe so that lair conlined therein can easily get out. The springs serve a further purpose, to wit: Ordinarily, in relasting a shoewithout interposing anything between the lining of the shoe and the last, the lining will cling to thelast ard become more or less puclrered, so that a thin strip of steel must -be inserted between the last and the lining and moved around within the shoe to straighten out the lining. By the use of the springs which I employ, the lining is so held away ,from the surface of the last materially changed without departing from the spirit of my invention.
